Applicationfifanuary 2, 1951, Serial No. iltlgliilv 2 Claims. (CL 222181l N invention relates to a'liolderunit for an alloy gage used bydentists, or their assistants.

An alloy gage, as referred to herein, has hitherto been operatedby handto dispense a certain amount of mercury and alloy, which, when proponehand and hold a funnel and an automatic mixer, or mortar, in the otherhand and place the latter in the right position relative to theunderside of the alloy gage is not an easy or practical operation.

In order to simplify and speed up this procedure and to create a safeand solid support and resting place for this valuable instrument, I havedevised and constructed a combination holder unit for an alloy gage,which may be mounted permanently in an upright position in a convenientplace, ready for instant use.

Another advantage of operating an alloy gage arranged in my devisedholder unit is, that it will always remain in the same steady, fixed andvertical position, so that the whole amount of mercury and alloyreleased from the alloy gage can drop without any hindrance into thefunnel of the device and into the automatic mixer (the latter not beingshown). This advantage can never be attained, when the alloy gage isheld in one hand and the funnel and automatic mixer in the other hand.

The holder unit is so constructed that the alloy gage can be refilledwith mercury and alloy while resting in said unit.

The said holder unit is of a durable and sturdy construction, and may bemade of metal, or any suitable material.

With the above and other objects in view, this invention consists of thenovel features of construction, combination and arrangement of parts,hereinafter fully described, claimed and illustrated in the accompanyingdrawing, forming part of this application, and in which similarcharacters of reference indicate corresponding parts in all views, andin which:

Figure l is a front elevational view of my holder unit proper, showingin dotted lines the alloy gage positioned thereon.

Figure 2 is a side elevational view of my device, as shown in Figure 1.

Figure 3 is a view taken on the line 3-3 of Figure 2.

Figure 4 is a transverse sectional view of the holder unit shown inFigure 2; while Figure 5 is a bottom view of my device, with a partbroken off.

erly mixed by hand, or mechanically, into, a compound, is used forfilling cavities in teeth.

To hold and manipulate an alloy gage with icularl'y'to the drawing, the

numeral fl 0 indicates'myholder comprising a one piece" unit having abottom ll, corrugated side flanges, lower at the front, as at I2, andhigher :at the rear as at I35 The device, further, has a back, or rear'plate M, which has its edges turned into a 'rearwardly extending rimportion I5 surrounding said'back.

The said rear plate I4 is provided with holes l6 therein adapted toreceive screws I! for securing the holder unit to a wall [8. The saidrear plate has an opening l9 therein in order to permit a rearwardmovement of a small adjustment plunger, or bolt 22, which cooperateswith the alloy gage shown herein in dotted lines at 20, but which doesnot otherwise form a part of this invention.

The rear plate I4 has Washer-like enlargements 2| formed at the rearthereof and flush with the edges of rearwardly extending rim portion I5,so as to provide suflicient space between the rear plate l4 and the Walll8 for the play of said plunger 22, when the latter in operating thealloy gage is pushed slightly backward.

The device is provided with a funnel 23 about centrally located at thebottom ll of the holder unit; said funnel being adapted to receive thematerial discharged by the alloy gage.

At the bottom of the holder unit is arranged a sliding spring member 24adapted for adjustment, so as to form a snug grip upon the alloy gage20. Said member consists of a piece of sprmgy material formed with anoblong slot 25 for said adjustment. The spring member 24, which is madewith rounded end portion 26, is adapted to slide between the ridges 21at the bottom I for steadying the movement of said member, which issecured underneath the bottom H of the holder unit by a screw 28.

The front wall 29 and part of the bottom II are made with cut-awayportions 30 and 3!. respgctively, adapted to receive said spring member4.

It is obvious that changes may be made in the form, construction andarrangement of the several parts, as shown, within the scope of theappended claims, without departing from the spirit of the invention, andI do not, therefore, wish to limit myself to the exact constructionshown and described herein.

What I claim as new, and desire to secure by Letters Patent of theUnited States, is:

I claim:

1. A device of the class described comprising in combination, a onepiece holder unit having four walls and being adapted to receive analloy 3 dispenser therein, said holder unit consisting of a low frontwall, a bottom having a funnel, low corrugated side walls terminating inupwardly extending portions, and a rear wall being provided with holes,said front Wall and bottom being each formed with a centrally cut-awayportion, ridges formed upon each side of the latter, and means slidablebetween saidoridg'es, whereby to accommodate different sizes ofdispensers, screws mounted in the holes of the rear wall securing theholder to a surface, said rear wallhaving a centrally located openingadapted to rceivefa plunger from said alloy dispenser, rearwardlyprojecting flanges surroundingthe"peripherygoi said rear wall andforming a space between the latter and said surface, whrebyto obtain sum1 cient play for said plunger.

2. A device of the class described comprising, A

formed upon each side'of the bottom cut-away .of. the'rear wall 'andsecuring the holder to a surface, said rear wall having a centrallylocated opening adapted to receive a plunger from said I valloydispenser, rearwardly projecting flanges I -surrounding -the peripheryof said rear wall and forming a space between the latter and saidsurface, whereby 'to obtain sufficient play for said plunger. 2
